حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مَسْلَمَةَ، عَنْ مَالِكٍ، عَنِ ابْنِ شِهَابٍ، عَنْ حُمَيْدِ بْنِ عَبْدِ الرَّحْمَنِ، أَنَّهُ سَمِعَ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ ـ رضى الله عنهما ـ يَوْمَ عَاشُورَاءَ عَامَ حَجَّ عَلَى الْمِنْبَرِ يَقُولُ يَا أَهْلَ الْمَدِينَةِ، أَيْنَ عُلَمَاؤُكُمْ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " هَذَا يَوْمُ عَاشُورَاءَ، وَلَمْ يُكْتَبْ عَلَيْكُمْ صِيَامُهُ، وَأَنَا صَائِمٌ، فَمَنْ شَاءَ فَلْيَصُمْ وَمَنْ شَاءَ فَلْيُفْطِرْ ".
ʿAbd Allāh ibn Maslamah related to us, from Mālik, from Ibn Shihāb, from Ḥumayd ibn ʿAbd al-Raḥmān, who heard Muʿāwiyah ibn Abī Sufyān (may Allah be pleased with them both) say from the pulpit on the Day of ʿĀshūrāʾ in the year he performed ḥajj: ‘People of Madinah, where are your scholars? I heard the Messenger of Allah (Allah bless him and grant him peace) say: “This is the Day of ʿĀshūrāʾ. Fasting it has not been prescribed for you, but I am fasting. So whoever wishes, let him fast, and whoever wishes, let him break his fast.”’
Translation notes
The Arabic says the speech occurred on the Day of ʿĀshūrāʾ in the year Muʿāwiyah performed ḥajj; that timing is retained.
